If you look at the links in the shared results on this thread there's 2 pages. The default one I got when I first went to the site is
https://redactle-unlimited.com/#article/VGhlX0JhaGFtYXM=
Which gives "The [7 letter word]
The other is the one you get if you click the Daily button is
https://redactle-unlimited.com/#article/Qmh1dGFu
Which is the same 6 letter word as the original redactle had before it disappeared.
I can't see any info on the page about when they change.
